WASHINGTON – Wesley Clark was registered as a lobbyist when he jumped into the presidential race, but he has yet to actually register as a presidential candidate – or even enroll as a Democrat.

Clark has yet to change his voter registration in his home state of Arkansas from independent to Democrat, BusinessWeek reported yesterday.

“This has been a whirlwind two weeks. There are a lot of things we have to do, and that’s one of them,” Clark spokesman Mark Fabiani told the mag.

The Federal Election Commission also said yesterday it still hasn’t received a statement of Clark’s candidacy, although the rules say a candidate must file a declaration within 15 days of spending or raising $5,000.

Clark announced his candidacy Sept. 17 – exactly 15 days ago – and his aides say they’ve already raised more than $2 million.

Clark’s opponents were having a field day yesterday with the retired general’s gaffes.

“The only question is whether he is a Democratic lobbyist or a Republican lobbyist,” scoffed Erik Smith, spokesman for Rep. Richard Gephardt (Mo.).

“I cannot believe that this party is even considering nominating someone who’s not only not a Democrat, but is a registered Washington lobbyist,” said Jano Cabrera, spokesman for Sen. Joe Lieberman (Conn.).

Fabiani said that formal papers terminating Clark’s lobbyist license were sent off yesterday.
